Near term (today through tonight)
issued at 200 am edt Sat apr 21 2018

Gradual warning trend continues...

high impact weather potential... None.

Pattern synopsis forecast... Large area of strong high pressure and
dry air remains centered over the great lakes region early this
morning... Resulting in clear skies and dry wx from the great lakes
thru the ohio valley into the SE us. Clear skies and calm winds are
allowing temps to slowly drop thru the 30s and into the 20s.

As we head into today and tonight... Strong surface high center will
remain overhead... Maintaining mostly clear and dry wx thru
tonight... With only some thin cirrus drifting overhead. Our gradual
warming trend will continue today with afternoon highs warming into
the 50s across our entire cwa. Temps will cool back into the 20s
tonight thanks to clear skies and calm winds.

Short term (Sunday through Monday)
issued at 200 am edt Sat apr 21 2018

Quiet and mild...

high impact weather potential: minimal, although will be monitoring
rising river levels through the weekend due to snow melt runoff.

Pattern forecast: split flow aloft across the CONUS is expected to
be evident this weekend with the primarily feature of note slowly
meandering across the central southern plains and a secondary system
across alberta saskatchewan. Both systems are expected to remain
well south north, respectively, of northern michigan as surface high
pressure dominates our weather locally through the weekend into the
start of the upcoming week.

Primary forecast concerns challenges: minimal aside from rising
rivers due to melting snow runoff into next week.

Little in the way of sensible weather is anticipated across northern
michigan right through the start of next week as aforementioned
surface high pressure sits atop the region. A return to near to
slightly above normal high temperatures is expected both Sunday and
Monday with highs topping out in the mid 50s nearest the lakeshores
to the low-upper 60s inland (normals for the third week of april
range from 52 at anj to 56 at tvc htl).

The biggest concern through the weekend into next week continues to
be snow melt runoff and resultant rises in area rivers. The rifle
river near sterling remains forecast to continue a slow rise above
flood stage Sunday afternoon while the manistee river near sherman
is forecast to fall half a foot or so short of minor flood stage.

Either way, the potential for area rivers to spill out of their
banks will need to be monitored through the weekend into next week.

Long term (Monday night through Friday)
issued at 200 am edt Sat apr 21 2018
high impact weather potential: minimal outside of rising river
levels.

Aside from the primary concern continuing to revolve around rising
river levels into next week, the focus lies in the late Tuesday
through Thursday timeframe as a quick-moving wave slides across the
central plains, perhaps interacting with the aforementioned southern
stream wave slowly moving across the southern tier of the CONUS late
this weekend. Low precipitation chances will be the result, mainly
from Tuesday night through the first half of Thursday.

Aviation (for the 06z tafs through 06z Saturday night)
issued at 1139 pm edt Fri apr 20 2018
vfr conditions to continue under a few passing high clouds. Light
wind through the period, so expect lake breezes at mbl, tvc, and
apn in the afternoon.

Marine
Issued at 200 am edt Sat apr 21 2018
winds and waves will remain below SCA criteria thru the weekend as
high pressure remains in charge of the wx across the great lakes
region. Dry wx and mainly clear skies are expected... With a
continuation of the gradual warming trend into next week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
